Silens Messor block chain

I would be grateful for advice on replacing the block chain on an 8" Silens Messor. The exising chain differs in pitch to the spokes on the wheel and is a very poor fit. Measured with digital callipers, the distance between the spokes appears to be 26.7mm, and the distance between the chain links is slightly larger at 27.2mm. Perhaps the chain has stretched a lot over the years, it's certainly very worn. I note that there's a link on the website to R M Fowler Ltd, and that they are offering a 1" pitch block chain. Has anyone tried this chain on a Silens Messor? Is it a good fit? Is it expensive? Are there any other sources?
